Hello everyone,

A few days ago i bought myself a Dell Precision M4700, I used it a day or two, at that time HDMI port was working well, but yesterday I accidently dropped my laptop, and since then HDMI is not working, the projector keeps on displaying no signal error. Does this mean that my HDMI port is gone? Are there anyways to confirm it?

P.S whenever i insert HDMI cable in my laptop it produces sound similar to when one insert a USB, pretty normal. But it does not work.

Thanks In Advance.

I think my problem is related to drivers, as whenever i insert the HDMI cable it produces sound of detecting. And I also have Nvidia Optimus enabled and hence two GPUs running at the same time i.e. Nvidia Quadro K1000M and intel HD 4000 graphics.
P.S please watch this video what my laptop do when i set the projection mode to DUPLICATE, (my laptop screen resolution decrease from 1080p to 720p).
